Storystore Fuel Line 1/4" (6mm) ID NBR Rubber Hose — 20 ft Black, 300 psi, -40–257°F

Storystore 1/4" (6 mm) ID fuel line is a 20-foot NBR rubber hose engineered for small engines and vehicle fuel systems that needs reliable fuel, oil and air transfer across a wide temperature range.

This heavy-duty NBR (nitrile butadiene rubber) hose from Storystore delivers a compact 6 mm internal diameter with a 12 mm outer diameter across 6 meters (20 ft) of flexible tubing. It’s designed for fuel, oil, diesel, biodiesel, grease, water and air applications where chemical resistance, temperature tolerance and pressure capacity matter. The hose balances light weight and portability with the mechanical performance required for automotive maintenance, small-engine repairs and custom routing jobs.

How does this hose handle heat and pressure in an engine bay?

The Storystore NBR fuel line works across a broad temperature window from -40 °F to 257 °F and supports a working pressure of 300 psi with a burst pressure up to 1160 psi. Those ratings make it resistant to typical under-hood temperature swings and capable of sustaining moderate system pressures without deformation.

• Operating temperature range: -40 °F to 257 °F
• Working pressure: 300 psi
• Burst pressure: 1160 psi
• Durable NBR construction for heat and chemical resistance

Can I use this hose with different fuels and oils?

Yes — the NBR compound is compatible with gasoline, diesel, biodiesel blends, oil and grease as well as air and water in routing or ventilation roles. Because some fuels and additives vary, always confirm chemical compatibility for long-term continuous exposure before installation.

• Compatible media: gasoline, diesel, biodiesel, oil, grease, water, air
• Suitable for fuel system lines, PCV and vapor routing
• Not intended for unsupported chemical exposures — verify specific additives

What are the physical dimensions and installation advantages?

The hose measures 1/4 inch (6 mm) internal diameter and 0.47 inch (12 mm) outer diameter in a continuous 20-foot length, offering flexibility for custom runs and spare parts stock. Its light weight and pliable profile make it easy to cut, clamp and route through cramped engine compartments or workshop setups.

• ID: 1/4 inch (6 mm); OD: 0.47 inch (12 mm)
• Length: 6 m / 20 ft continuous roll
• Easy to cut to length and fit with standard clamps and fittings
• Portable roll for field repairs and workshop use

How long will it last and where should I avoid using it?

Storystore’s NBR hose is formulated for durability under typical automotive and small-engine conditions, but longevity depends on exposure to harsh chemicals, ozone, extreme abrasion or continuous high heat beyond rated limits. Avoid direct contact with concentrated solvents, prolonged UV exposure without protection, and applications exceeding the stated pressure or temperature ratings.

• Resists typical automotive fuels and oils for general-use longevity
• Avoid continuous UV exposure and aggressive solvents
• Check system temperature and pressure to ensure safe service life

Who is this for: Technicians, hobbyists and vehicle owners who need a reliable, flexible fuel line for small engines, motorcycles, lawn equipment, generators and custom fuel routing. It’s also useful for workshops that require a stocked, multi-purpose hose for fuel, oil or air work — especially where compact diameter and a long continuous length simplify installations and repairs.
